Installing Kivy on Raspberry with Raspbian is a bit tricky. There are some good instructions found online but non of them worked completely. Especially if you have a Raspberry Pi 3B+ and the RaspiLCD combined.
Follow the instructions here on kivy.org to install kivy on Raspbian (Jessie/Stretch)
Just use Step 1 - 3 (This will work but take a bit)
Be aware that you might have to use pip3 instead of pip if you have python 2.7 already installed. Also install Cython without using a version string. Just install latest greatest. To check that run pip --version to see to which folder pip will install the packages.
Maybe considering using not the Master branch, there is also a branch called stable-1.10 if you want to go on a more stable version.
Clone the Kivy Git Repo here, go to ./kivy/examples/demo/touchtracer/ and edit the main.py according to the instructions above.
import os
os.environ['KIVY_GL_BACKEND'] = 'gl'
import kivy
Run with python3 main.py
This File will only exist after the first "failed" run.
[input]
mouse = mouse
device_%(name)s = probesysfs,provider=mtdev
mtdev_%(name)s = probesysfs,provider=mtdev
hid_%(name)s = probesysfs,provider=hidinput
Run with python3 main.py
Copy kivy Script from this repo to /etc/init.d/kivy and adjust the path to your application.
Run sudo update-rc.d kivy defaults as root
Reboot
Enjoy!
Just open an issue ;)
